Extended Result Codes, Dial Tone Detect, Busy Tone
Detect
This command controls three different configuration
options.
Extended Result Codes allow additional information to
be displayed with the result code.
Dial Tone Detect, if enabled, causes the modem to
wait (up to 10 seconds) for a dial tone before dialing. If
disabled (also known as blind dialing), the modem
dials the call regardless of dial tone detection.
NOTE:
Blind Dialing is not supported in some
countries outside of North America. Therefore, dial
tone detection cannot be disabled in those countries.
See Table 4-3 for more information.
Busy Tone Detect, if enabled, sets the modem to
monitor for a busy tone. If disabled, the modem
ignores busy tones.
